They all fit a niche in the MU and the MCU at that.

Captain Marvel and Black Panther made over a billion with each of their films, something that other related franchises at the moment have struggled with. They aren't going to demote them because they have a 20 year old franchise that's failed with their last two movies. If anything, Wolverine will be the face of the X-Men and join the Avengers.

They did turn Spidey around, but included him on the Avengers fun to tie them better.
Actually there have been a surprising amount of non-mutant members of each X-team and the mythos. More than what can be counted on "one hand". Also, I expect Marvel Studios to be smart enough NOT to overexpose Wolverine like Fox.
